Jujutsu (jj) Version Control

Agent Usage

When reading data from jj, always use --ignore-working-copy to avoid snapshotting the working copy (which is slow and unnecessary for read operations).

Non-interactive Commands (Critical)

Many jj commands spawn $EDITOR or interactive diff tools by default. These will hang indefinitely when run by agents. Always use the non-interactive alternatives:

Command	Problem	Solution
`jj describe`	Opens editor	Always use `-m "message"`
`jj commit`	Opens editor	Always use `-m "message"`
`jj split`	Opens diff editor + may open editor for description	Provide filesets to select files; use `-m` for description
`jj squash`	May open editor for combined description	Use `-m "message"` or `-u` (use destination message)
